This application claims the U.S. Non-provisional Patent application the 13/589th submitted on August 17th, 2012, the rights and interests of No. 004, its open text by reference entirety is incorporated to herein.

Background of invention

Present invention relates in general to the coking equipment field for being produced coke by coal.Coke is for melting and the solid carbon fuel of reducing iron ore and carbon source in Iron and Steel Production.Be called in the technique of " Tang Pusen coke making process (Thompson Coking Process) " in one, by coal dust is added in stove in batches, seal described stove and heat 24-48h to excessive temperature under the atmospheric condition of strict control, producing coke.Pit kiln has used for many years, for coal is converted into metallurgical coke.In process of coking, under controlled temperature condition, heat coal in small, broken bits be coal removing volatile substances and form the coke melt with predetermined porosity and intensity.Because the production of coke is batch process, operate multiple coke oven simultaneously.

The fusing that in heat-processed, coal grain experiences and alloying process are the integral parts of coking.Coal grain is converted into the characteristic that the fusing degree of melt substance and assimilation degree determine produced coke.In order to produce the hardest coke by specific coal or Mixture Density Networks, in coal, there is optimum proportion that is active and inertia entity.The porosity of coke and intensity are very important and determined by coal source and/or coking process for ore refining process.

Coal grain or Mixture Density Networks grain are loaded in hot stove, and coal heats to remove volatile matter from generated coke in stove.Coke making process height depends on stove design, coal type and the invert point of use.Regulating stove during coke making process, so that each coal all coking within the roughly the same time loaded.Once coal " coking " or coking completely, just coke shifted out in stove and use water quenching to be cooled to lower than its kindling temperature.Alternatively, rare gas element dry quenching(of coke) is used.Quenching operation also must carefully control, so that coke can not absorb too many moisture.Once quenching, load rail car or truck transports with regard to screening coke.

Because coal is added in hot stove, so most of coal process automation.In slot type or vertical heater, usually coaling by the groove in furnace roof portion or opening.This stove is often not only high but also narrow.Horizontal non-recycled or recovery of heat class pit kiln are also for the production of coke.In non-recycled or recovery of heat class pit kiln, with transfer roller, coal grain is conveyed horizontally in stove to provide elongated coal seam.

Along with the coal source of applicable formation metallurgical coal (" coking coal ") is reduced, attempt inferior or inferior quality coal (" non-coking coal ") to mix to provide the coal charge being suitable for described stove with coking coal.A kind of mode merging non-coking coal and coking coal uses compacting or coal tamping.Can by coal compacting before or after it enters in stove.In some embodiments, by the mixture compacted of non-coking coal and coking coal to higher than 50 pounds/cubic feet, non-coking coal is used for coke making process.Along with the per-cent of non-coking coal in coal mixtures increases, need higher coal compacting level (such as, up to about 65-75 pound/cubic feet).Commercial, usually coal is densified to about 1.15-1.2 proportion (sg) or about 70-75 pound/cubic feet.

Based on the relative operation atmospheric pressure of furnace interior, horizontal recovery of heat (HHR) stove and accessory has the unique environments advantage being better than chemical by-product stove.HHR stove works under a negative pressure, and chemical by-product stove is at slightly positive operated at atmospheric pressure.Two kinds of stove types are usually built by refractory brick and other material and are formed, wherein because may form crackle in these structures during regular job, so setting up airtight environment substantially may be a challenge.Chemical by-product stove is kept at a positive pressure in order to avoid be oxidized recyclable product and make stove overheated.On the contrary, HHR stove is kept under a negative pressure, suck air from stove outside and in stove, discharge the combustion heat with oxidized coal volatile matter.These contrary working pressure conditions and firing system are design difference important between HHR stove and chemical by-product stove.Because the loss of the volatile gases of entered environment is reduced to minimum very important, so the combination of positive atmospheric condition and little opening or crackle makes coal oven dithio-gas (" COG ") and noxious pollutant leak in air in chemical by-product stove.On the contrary, in HHR stove or the negative atmospheric condition of coking equipment elsewhere and little opening or crackle only make additional air suck in stove or coking equipment elsewhere so that negative atmospheric condition prevent COG to the loss of air.

More CONSTRUCTED SPECIFICATION of each stove 105 are shown in Fig. 2, have wherein described the different piece of 4 coke ovens 105 for clear period cuts cross section and be also illustrated in figure 3.Each stove 105 includes an open cavity, is limited by base plate 160, the Qianmen 165, preferably back door 170, two sidewalls 175 upwards extended from the base plate 160 in the middle of Qianmen 165 and back door 170 and the top 180 that forms furnace chamber 185 open cavity upper surface forming the stove whole side relative with Qianmen substantially relative to Qianmen 165 that form the whole side of stove substantially.It can be vital for controlling the air flow quantity of furnace chamber 185 inside and pressure for the valid function of coking cycle, and therefore Qianmen 165 comprises the one or more primary air entrances 190 making primary combustion air enter furnace chamber 185.Each primary air entrance 190 includes primary air baffle plate 195, and it can be positioned fully open and fully closed being permitted and multipointly arbitraryly sentence the amount changing and enter an air-flow of furnace chamber 185.Alternatively, described one or more primary air entrance 190 can be formed through top 180.During work, from be positioned at furnace chamber 185 inside coal discharge volatile gases collection top and suck downwards in the entire system one or two sidewall 175 formation sending down abnormally ascending tube passage 200.Furnace chamber 185 is connected with sole flue 205 fluid be positioned under drop-bottom 160 by sending down abnormally ascending tube passage.Sole flue 205 forms circuitous path 160 times at drop-bottom.The volatile gases discharged from coal can burn at sole flue 205, thus produces heat to support that coal is reduced to coke.Sending down abnormally ascending tube passage 200 is connected with the chimney that one or two sidewall 175 is formed or rising passway 210 fluid.Between sole flue 205 and air, be provided with secondary air entrance 215 and secondary air entrance 215 comprises secondary air baffle plate 220, it can be positioned fully open and fully closed being permitted and multipointly arbitraryly sentence the amount changing and enter the secondary gas flow of sole flue 205.Rising passway 210 is connected with total tunnel 110 fluid by one or more rising air flue 225.Tertiary air entrance 227 is provided with between rising air flue 225 and air.Tertiary air entrance 227 comprises tertiary air baffle plate 229, can be positioned fully open and fully closed being permitted and multipointly arbitraryly sentence the amount changing and enter three air-flows of rising air flue 225.

In order to provide the ability controlled by the gas flow in rising air flue 225 and stove 105, each rising air flue 225 also comprises uptake baffle plate 230.Uptake baffle plate 230 can be positioned the fully open and fully closed position of arbitrary quantity to change the furnace ventilation in stove 105.As used herein, " ventilation " refers to the negative pressure relative to air.Such as, the ventilation of 0.1 inch of water refers to the subatmospheric pressure of 0.1 inch of water.Inches of water be pressure non SI units and by convention for being described in the ventilation of coking equipment different positions.Increase or make it larger if ventilated, pressure moves to below normal atmosphere further.Reduce if ventilated, reduce or make it less or lower, pressure moves to normal atmosphere.By controlling to ventilate in stove with uptake baffle plate 230, the gas leakage entering the air-flow in stove 105 from gas inlet 190,215,227 and enter in stove 105 can be controlled.Usually, as shown in Figure 3, stove 105 comprises two rising air flues 225 and two uptake baffle plates 230, but uses two rising air flues and two uptake baffle plates and unnecessary, can design system to only with one or more rising air flue and two uptake baffle plates.

As shown in Figure 1, sample HHR coking equipment 100 comprises many stoves 105 that can be divided into stove group 235.The HHR coking equipment 100 illustrated comprises 5 stove groups 235, each 20 stoves, amounts to 100 stoves.Whole stove 105 is all connected with total tunnel 110 fluid by least one rising air flue 225, and total tunnel 110 is connected with each HRSG 120 fluid by air crossing 115 successively.Each stove group 235 is connected with specific air crossing 115.Waste gas from stove 105 each in stove group 235 flows into by total tunnel 110 air crossing 115 be connected with respective each stove group 235.Half stove in stove group 235 is arranged in the side of intersection point 245 of total tunnel 110 and air crossing 115 and second half stove of stove group 235 is positioned at the opposite side of intersection point 245.

The HRSG valve be connected with each HRSG 120 or baffle plate 250 (as shown in Figure 1) are adjustable as the exhaust gas flow controlled by HRSG 120.HRSG valve 250 can be positioned on the upstream of HRSG120 or hot side, but is preferably located at downstream or the cold side of HRSG 120.HRSG valve 250 can fade to fully open and fully closed many positions and control the exhaust gas flow by HRSG 120 by the relative position of adjustment HRSG valve 250.

During work, by first coal being loaded furnace chamber 185, under anaerobic environment, adding hot coal, distillating the volatile part of coal, the volatile matter then in oxidized still 105, to catch and to utilize the heat discharged, produces coke.At the coking cycle of about 48h, coal volatile matter is at stove internal oxidition, and release of heat is with the coal carbonization coke of regenerative drives.Coking cycle door 165 starting when coal being loaded drop-bottom 160 before opening.Coal on drop-bottom 160 is also referred to as coal seam.Heat from stove (due to previous coking cycle) starts the carbonization cycle.Preferably, except the fuel generated by described coke making process, do not use other fuel.The only about half of total heat biography amount to coal seam is from the flare in coal seam and radiation furnace roof 180 downward radiation to coal seam upper surface.The heat of residue half is delivered to coal seam by conduction from the drop-bottom 160 because of the gaseous volatilization convective heating sole flue 205.Like this, the carbonization process " ripple " of coal grain plastic flow and the formation of high strength sticky coke are carried out with the lower edges of phase same rate from coal seam, preferably converge at the center in coal seam after about 45-48h.

Due to various reason, comprise for guaranteeing the complete coking of coal, all combustions heat are effectively extracted from volatile gases, with the oxygen level in other place of coking equipment 100 in effective control furnace chamber 185, control particulate and other potential pollutant and the latent energy in waste gas be converted into the steam that can be used for producing steam and/or electricity, accuracy-control system pressure, furnace pressure, the air flow quantity entered in stove, the air flow quantity entering system and intrasystem gas flow are very important.Preferably,

Operate each stove 105 under negative pressure, so because the pressure reduction between stove 105 and air is by air intake stove in reduction process.The primary air being used for burning is added furnace chamber 185 with partial oxidation coal volatile matter, but the amount of this primary air is preferably controlled, make an only part from the volatile matter of coal release in furnace chamber 185 combustion, thus its enthalpy of combustion in furnace chamber 185 of an only release part.By primary air entrance 190, primary air is introduced the top in coal seam in furnace chamber 185, controlled the amount of primary air by primary air baffle plate 195.Primary air baffle plate 195 also can be used for maintaining the required working temperature in furnace chamber 185.Partially combusted gas enters sole flue 205 from furnace chamber 185 through sending down abnormally ascending tube passage 200, and secondary air adds in partially combusted gas here.Introduce secondary air by secondary air entrance 215, controlled the amount of the secondary air introduced by secondary air baffle plate 220.When introducing secondary air, partially combusted gas burns more fully in sole flue 205, thus extracts afterburning enthalpy, increases heat by drop-bottom 160 conveying for furnace chamber 185.Abundant or almost clean-burning waste gas leave sole flue 205 by rising passway 210, then flow into rising air flue 225.Via tertiary air entrance 227, tertiary air is added in waste gas, controlled the amount of the tertiary air introduced here by tertiary air baffle plate 229, make any remainder of unburned gas in waste gas in tertiary air entrance 227 downstream oxidation.

At the end of coking cycle, coal coking and carbonization and generate coke.Green coke is the coal of not fully coking.Preferably by back door 170, mechanical extraction system is utilized to be shifted out from stove 105 by coke.Finally, quenching (such as, wet method or dry quenching(of coke)) and sieving before consigning to user.

Fig. 4 describes a part for the coking equipment 100 comprising ventilation automatic control system 300.Ventilation automatic control system 300 comprises arbitrary furnace ventilation amount sentenced in change stove 105 that can be positioned in fully open and fully closed many positions.The working conditions that detects in response at least one sensor (pressure or ventilation, temperature, oxygen concn, gas flow rate), controls automatic uptake baffle plate 305.Automatic control system 300 can comprise one or more sensor discussed below or be configured to detect other sensor of the working conditions relevant to the work of coking equipment 100.

Furnace ventilation sensor or furnace pressure sensor 310 detect the pressure that represents furnace ventilation and furnace ventilation sensor 310 can be arranged in other of furnace roof 180 or furnace chamber 185 local.Alternatively, furnace ventilation sensor 310 can be positioned at arbitrary automatic uptake baffle plate 305 place, in sole flue 205, and arbitrary fire door 165 or 170 place, or near coke oven 105 or in the total tunnel 110 of top.In one embodiment, furnace ventilation sensor 310 is positioned at the top of furnace roof 180.Furnace ventilation sensor 310 with the firebrick lining positioned flush of furnace roof 180 or can stretch in furnace chamber 185 from furnace roof 180.Bypassed exhaust gas flue draught sensor 315 detects the pressure of the ventilation representing bypassed exhaust gas flue 240 place (such as, in the bases of bypassed exhaust gas flue 240).In some embodiments, bypassed exhaust gas flue draught sensor 315 is positioned at intersection point 245 place.Other ventilation sensor can be positioned at other position of coking equipment 100.Such as, the ventilation sensor in total tunnel can be used for detecting the total tunnel ventilation of the furnace ventilation in the multiple stoves representing contiguous ventilation sensor.Intersection point ventilation sensor 317 detects the pressure of the ventilation representing one of them intersection point 245 place.

Furnace temperature sensor 320 detects furnace temperature and can be positioned at furnace roof 180 or other place of furnace chamber 185.Sole flue temperature sensor 325 detects sole flue temperature and is positioned at sole flue 205.In some embodiments, sole flue 205 is divided into two lost 205A and 205B, each getting lost is communicated with the fluid of two rising air flues 225 of stove.Flue temperature sensor 325 is arranged in each sole flue and gets lost, so that can detect the sole flue temperature in each getting lost.Rising airway temperature sensor 330 detects rising airway temperature and is positioned at rising air flue 225.Total tunnel temperature sensor 335 detects total tunnel temperature and is positioned at total tunnel 110.HRSG inlet temperature sensor 340 detect HRSG temperature in and can be positioned at HRSG 120 ingress or near.Other temperature sensor can be positioned other position in coking equipment 100.

Rising air flue oxygen sensor 345 orientates the oxygen concn detecting waste gas in rising air flue 225 as.HRSG entrance oxygen sensor 350 orientates the oxygen concn of the ingress waste gas detecting HRSG 120 as.Flue collector oxygen sensor 360 orientates the oxygen concn that detects waste gas in flue collector 145 as and other oxygen sensor can be positioned on other position in coking equipment 100 to provide the information of the relative oxygen concn about different positions in system.

Flow sensor detects the gas flow rate of waste gas.Such as, flow sensor can be positioned at the downstream of each HRSG 120 to detect the flow velocity leaving the waste gas of each HRSG 120.This Information Availability is in being balanced the exhaust gas flow by each HRSG 120 by adjustment HRSG baffle plate 250.Other flow sensor can be positioned other position in coking equipment 100 to provide the information of the gas flow rate about different positions in system.

In addition, one or more ventilation or pressure transmitter, temperature sensor, oxygen sensor, flow sensor and/or other sensor can be used in other position in AQS 130 place or HRSG 120 downstream.

Importantly keep sensors clean.A kind of method of sensors clean is kept to be regular dismounting sensor and Manual-cleaning.Alternatively, can make that regular sensor stands for a moment, the high pressure gas of one or flowing to be to remove the blocking on sensor.Further alternatively, continuous little airflow can be provided with continuous cleaning sensor.

Automatic uptake baffle plate 305 comprises uptake baffle plate 230 and is the actuator 365 opening and closing the configuration of uptake baffle plate 230.Such as, actuator 365 can be linear actuators or revolving actuator.Actuator 365 can make uptake baffle plate 230 infinitely be controlled between fully open and fully closed position.The working conditions that actuator 365 detects in response to the sensor included by ventilation automatic control system 300, makes uptake baffle plate 230 move between these positions.Which provide the control more much better than than traditional uptake baffle plate.The fully open and fully closed number of positions of tradition uptake baffle plate is limited and must by operator's manual regulation between these positions.

Periodic adjustment uptake baffle plate 230 is to maintain suitable furnace ventilation (such as, at least 0.1 inch of water), and furnace ventilation changes in response to stove or the intrasystem many Different factor of hot thermal exhaust.When total tunnel 110 has relatively low total tunnel ventilation (that is, than relatively high ventilation closer to barometric point), can open uptake baffle plate 230 increases furnace ventilation to guarantee that furnace ventilation maintains 0.1 inch of water or more.When total tunnel 110 has relatively high total tunnel ventilation, uptake baffle plate 230 can be closed and reduce furnace ventilation, thus reduce the air capacity sucking furnace chamber 185.

About traditional uptake baffle plate, manual regulation uptake baffle plate, therefore optimizing furnace ventilation half is art, and half is science, is the product of operator's experience and understanding.Ventilation automatic control system 300 as herein described makes the auto-control of uptake baffle plate 230 and allows the position of Filled function uptake baffle plate 230, thus instead of operator's experience and the understanding of at least some necessity.Ventilation automatic control system 300 can be used for furnace ventilation being maintained stove target ventilation (such as, at least 0.1 inch of water), controls the amount of surplus air in stove 105, or by automatically regulating the position of uptake baffle plate 230 to realize other ideal effect.Without automatically controlling, if not impossible, being also difficult to as required manual regulation uptake baffle plate 230 continually and, to maintain the furnace ventilation of at least 0.1 inch of water, and not making furnace pressure turn to positive number.Usually, with Non-follow control, stove target ventilation, higher than 0.1 inch of water, causes more air to bleed coke oven 105.For traditional uptake baffle plate, operator monitor different furnace temperature and the coking of visually observing in coke oven is how many with adjustment to determine when regulating uptake baffle plate.Operator are not about the specifying information of ventilate in coke oven (pressure).

Actuator 365 is indicated to uptake baffle plate 230 according to the position received from controller 370 and locates.The ventilation that can detect in response to one or more sensor discussed above, temperature, oxygen concn, gas flow rate, comprise control algolithm or other control algolithm of the input of one or more sensor, generate position instruction.Controller 370 can be associated with single automatic uptake baffle plate 305 or multiple automatic uptake baffle plate 305 discrete controller, Centralized Controller (such as, dcs or programmable logic control system) or two kinds combination.In some embodiments, controller 370 proportions of utilization-Integrated Derivative (PID) controls.

Such as, the furnace ventilation that ventilation automatic control system 300 can detect in response to furnace ventilation sensor 310 controls the automatic uptake baffle plate 305 of stove 105.Furnace ventilation sensor 310 detects furnace ventilation and exports the signal representing furnace ventilation to controller 370.Controller 370 generates position instruction in response to the input of this sensor and uptake baffle plate 230 is moved on to the position that position instruction requires by actuator 365.Like this, automatic control system 300 can be used for maintaining stove target ventilation (such as, at least 0.1 inch of water).Similarly, ventilation automatic control system 300 can control automatic uptake baffle plate 305, HRSG baffle plate 250 and vacuum fan 140 as required, target ventilation (such as, intersection point target ventilation or total tunnel target ventilation) is maintained with other position in coking equipment 100.Ventilation automatic control system 300 can be placed in manual mode to allow the automatic uptake baffle plate 305 of manual regulation as required, HRSG baffle plate and/or vacuum fan 140.Preferably, ventilation automatic control system 300 comprise manual mode timing register and once manual mode timing register then, ventilation automatic control system 300 just can revert to automatic mode.

In some embodiments, the signal of the pressure that the expression that furnace ventilation sensor 310 generates detects or ventilation is on average for realizing the time that steady pressure controls in coke oven 105.Can by the time average of controller 370 settling signal.The time of mean pressure signal contributes to the normal fluctuation that filters out in pressure signal and is filled into noise.Usually, can at 30s, 1min, 5min or at least average signal in 10min.In one embodiment, by carrying out 200 scanning to the pressure detected, scan 50ms at every turn, generate the rolling time mean value of pressure signal.The difference of time-averaged pressure signal and stove target ventilation is larger, and the baffle position change that ventilation automatic control system 300 is formulated is greatly to reach required target ventilation.In some embodiments, the difference of the controller 370 position instruction that is supplied to automatic uptake baffle plate 305 and time-averaged pressure signal and stove target ventilation linearly.In other embodiments, controller 370 is supplied to the position instruction of automatic uptake baffle plate 305 and the non-linear ratio of difference of time-averaged pressure signal and stove target ventilation.Time-averaged signal can be had like other sensor class previously discussed.

Ventilation automatic control system 300 can be operated to be maintained within the scope of the certain tolerance of stove target ventilation by time-averaged stove constant draft at whole coking cycle.Such as, this tolerance can be +/-0.05 inch of water, +/-0.02 inch of water or +/-0.01 inch of water.

Also ventilation automatic control system 300 can be operated to produce variable ventilation by regulating stove target ventilation in coking cycle process on coke oven.According to coking cycle elapsed time, progressively can reduce stove target ventilation.By this way, for the coking cycle of 48h, target ventilation start relatively high (such as, 0.2 inch of water) and every 12h reduces by 0.05 inch of water, stove target ventilation is made to be 0.2 inch of water at the 1-12h of coking cycle, be 0.15 inch of water at the 12-24h of coking cycle, be 0.01 inch of water at the 24-36h of coking cycle, and be 0.05 inch of water at the 36-48h of coking cycle.Alternatively, at whole coking cycle, target ventilation can be linearly reduced to the less new value proportional with coking cycle elapsed time.

Such as, if the furnace ventilation of stove 105 is reduced to stove target ventilation (such as, 0.1 inch of water) below and uptake baffle plate 230 open completely, then ventilation automatic control system 300 will increase furnace ventilation by opening at least one HRSG baffle plate 250, and increase ventilate.Because the increase that stove 105 downstream ventilates has influence on more than one stove 105, some stoves 105 may need to regulate its uptake baffle plate 230 (such as, move towards the position closed completely) to maintain stove target ventilation (that is, regulating stove ventilates in case it becomes too high).If HRSG baffle plate 250 is opened completely, then ventilation automatic control system 300 will need the ventilation allowing vacuum fan 140 provide larger.The ventilation of this increase in all HRSG 120 downstreams will affect all HRSG120 and may need to regulate HRSG baffle plate 250 and uptake baffle plate 230 to maintain the target ventilation of whole coking equipment 100.

For another example, to open completely by requiring at least one uptake baffle plate 230 and so stove 105 is at least in stove target ventilation (such as, 0.1 inch of water) under, regulate HRSG baffle plate 250 and/or vacuum fan 140 to maintain these operational requirements as required, total tunnel ventilation is reduced to minimum.

For another example, intersection point is ventilated and/or has coking equipment 100 for tunnel ventilation and can run under variable ventilation with the temperature of stable leak rate, mass rate and waste gas and composition (such as oxygen level), and other desired gains.This changes by being ventilated by intersection point and/or having tunnel ventilation from relatively high ventilation during propelling coke oven 105 and reduces to relatively low ventilation gradually (such as, 0.4 inch of water), namely run under relatively high ventilation at coking cycle early stage and run under relatively low ventilation in the later stage of coking cycle.Ventilation can be changed continuously or by progressively mode.

For another example, if total tunnel ventilation reduces too many, then HRSG baffle plate 250 can be opened to raise total tunnel ventilation to meet total tunnel target ventilation (such as, 0.7 inch of water) along one or more positions in total tunnel 110.Increase after having tunnel ventilation by regulating HRSG baffle plate 250, uptake baffle plate 230 in adjustable affected stove 105 (such as, move to complete off-position) to maintain the stove target ventilation (that is, regulating stove ventilates in case it becomes too high) in affected stove 105.

For another example, the furnace temperature that ventilation automatic control system 300 can detect in response to furnace temperature sensor 320 and/or the sole flue temperature that sole flue temperature sensor 325 detects, control the automatic uptake baffle plate 305 of stove 105.Regulate automatic uptake baffle plate 305 can according to appointment optimum furnace coke production or other expected result in response to furnace temperature and/or sole flue temperature.When sole flue 205 comprises two lost 205A and 205B, then the temperature equilibrium that can control between two lost 205A and 205B by ventilation automatic control system 300.In response to the sole flue temperature that the sole flue temperature sensor 325 being positioned at lost 205A or 205B be associated with this rising air flue 225 detects, control the automatic uptake baffle plate 305 of each of stove two rising air flues 225.Controller 370 compare lost 205A and 205B each in the sole flue temperature that detects be that each of two automatic uptake baffle plates 305 generates position instruction, the sole flue temperature in each of lost 205A and 205B is all remained in specified for temperature ranges.

In some embodiments, two automatic uptake baffle plates 305 move to same position or synchronous together.Automatic uptake baffle plate 305 near Qianmen 165 is called " propelling side " baffle plate and automatic uptake baffle plate 305 near back door 170 is called " coke side " baffle plate.By this way, single furnace ventilation pressure transmitter 310 provides signal and advances side and the automatic uptake baffle plate 305 in coke side for regulating equally.Such as, open if be designated as 60% to the position of automatic uptake baffle plate 305 by controller, then advance side and coke side automatic uptake baffle plate 305 equal 60% to open location.If be designated as to the position of automatic uptake baffle plate 305 by controller open 8 inches, then side and the automatic uptake baffle plate 305 in coke side is advanced all to open 8 inches.Alternatively, two automatic uptake baffle plates 305 move to different positions and cause deviation.Such as, for the deviation of 1 inch, if will for opening 8 inches to the position instruction of synchronous uptake baffle plate 305 automatically, then for biased automatic uptake baffle plate 305, one of them automatic uptake baffle plate 305 will open 9 inches and another automatic uptake baffle plate 305 will open 7 inches.Time compared with synchronous uptake baffle plate 305 automatically, biased automatic uptake baffle plate 305 is always opened area and pressure drop keeps constant.As required, automatic uptake baffle plate 305 can be operated with synchronous or bias mode.Deviation can be used for attempting maintaining equal temperature in the propelling side of coke oven 105 and coke side.Such as, the sole flue temperature recorded in each lost 205A and 205B of sole flue (another is advancing side in coke side) can be measured, then adjustable corresponding uptake baffle plate 305 is automatically to reach stove target ventilation, uses coke side simultaneously and advances the difference of wing furnace bottom flue temperature to introduce and coke wing furnace bottom flue and the deviation that advances the difference of sole flue temperature between wing furnace bottom flue proportional.Like this, can make to advance side equal in a certain range of tolerable variance with coke wing furnace bottom flue temperature.Tolerance (difference of coke side and propelling wing furnace bottom flue temperature) can be 250 °F, 100 °F, 50 °F or preferably 25 °F or lower.Use state-of-the-art Method and Technology, coke wing furnace bottom flue can be made at one or more hours in (such as 1-3h) process and advance wing furnace bottom flue temperature in mutual tolerance, control furnace ventilation simultaneously and reach stove target ventilation in specified tolerance (such as +/-0.01 inch of water) scope.According to the sole flue temperature recorded in each lost 205A and 205B of sole flue, biased automatic uptake baffle plate 305, makes heat transmit in the propelling side of coke oven 105 and coke side.Usually, because the propelling side of coke bed and coke side are with different rates coking, so need heat from propelling sidesway to coke side.Equally, according to the sole flue temperature recorded in each lost 205A and 205B of sole flue, biased automatic uptake baffle plate 305, under contributing to, on whole base plate, drop-bottom is maintained relatively average temperature.

Furnace temperature sensor 320, sole flue temperature sensor 325, rising airway temperature sensor 330, total tunnel temperature sensor 335 and HRSG inlet temperature sensor 340 can be used for detecting the superheat state of its each position separately.These temperature detected can generate position instruction to make excess air enter one or more stove 105 by opening one or more automatic uptake baffle plate 305.Excess air (that is, the oxygen of existence is higher than the stoichiometric ratio for burning) produces unburned oxygen and unburned nitrogen and produces waste gas in stove 105.The temperature of this excess air is lower than other waste gas and provide the cooling performance of superheat state eliminating other place of coking equipment 100.

For another example, the rising air flue oxygen concn that ventilation automatic control system 300 can detect in response to rising air flue oxygen sensor 345 controls the automatic uptake baffle plate 305 of stove 105.Can in response to rising air flue oxygen concn regulate automatic uptake baffle plate 305 with the waste gas Thorough combustion guaranteeing to leave stove 105 and/or leave stove 105 waste gas not containing too much excess air or oxygen.Similarly, the HRSG inlet oxygen concentration that can detect in response to HRSG entrance oxygen sensor 350 regulates automatic uptake baffle plate 305 to keep HRSG inlet oxygen concentration higher than threshold concentration, and protection HRSG 120 avoids the waste gas unwanted combustion occurred at HRSG 120 place.HRSG entrance oxygen sensor 350 detects minimum oxygen concn to guarantee that all inflammable substance burnt before entering HRSG 120.Equally, the flue collector oxygen concn that can detect in response to flue collector oxygen sensor 360 regulates automatic uptake baffle plate 305 to reduce the impact of leaking gas to coking equipment 100.This gas leakage can be detected according to the oxygen concn in flue collector 145.

Ventilation automatic control system 300 also can control automatic uptake baffle plate 305 according to elapsed time in coking cycle.Such permission controls automatically, need not install furnace ventilation sensor 310 or other sensor in each stove 105.Such as, based on from the one or more coke oven 105 previously history actuator position data of coking cycle or baffle position data, so that automatic uptake baffle plate 305 can be controlled based on the historical location data relevant with elapsed time in current coking cycle to the instruction of the position of automatic uptake baffle plate 305.

Ventilation automatic control system 300 also can in response to the automatic uptake baffle plate 305 of sensor input control from one or more sensor discussed above.Reasoning and decision makes according to stove or coking equipment working conditions (such as, ventilation/pressure, temperature, the oxygen concn of different positions in stove 105 or coking equipment 100) expection change control each coke oven 105, and the actual operating conditions detected not to be reacted.Such as, use reasoning and decision, based on the multiple readings from furnace ventilation sensor in for some time, the display furnace ventilation detected towards stove target ventilation (such as, at least 0.1 inch of water) decline furnace ventilation change, can be used for expecting that the prediction furnace ventilation lower than stove target ventilation drops to the actual furnace ventilation of below stove target ventilation with expection and generates position instruction to change the position of automatic uptake baffle plate 305 in response to expection furnace ventilation according to prediction furnace ventilation, and not etc. actual furnace ventilation did not drop to below stove target ventilation before the instruction of generation position.Reasoning and decision can be used for the interaction considered between the different operating condition of different positions in coking equipment 100.Such as, consider the needs always kept by stove under a negative pressure, needed for controlling to, the suitableeest furnace temperature, sole flue temperature and minimum total tunnel temperature, reduce to minimum reasoning and decision by furnace ventilation simultaneously, locates for giving automatic uptake baffle plate 305.The working conditions input that reasoning and decision makes controller 370 provide according to the above-mentioned different sensors of known coking cycle characteristic sum, makes a prediction.Another example of reasoning and decision make the automatic uptake baffle plate 305 of each stove 105 modulated with optimizing in coke yield, the control algolithm forming optimum balance between coke quality and generated energy.Alternatively, to make coke yield, coke quality and generated energy, one of them reaches the highest to adjustable automatic uptake baffle plate 305.

Alternatively, similar ventilation automatic control system can be used for making primary air baffle plate 195, secondary air baffle plate 220 and/or tertiary air baffle plate 229 automatization, to control rate of combustion and the position of different positions in stove 105.Such as, can in response to the proper sensors be positioned in sole flue 205 or to be positioned in ventilation that the proper sensors in each lost 205A and 205B of sole flue detects, temperature and oxygen concn one or more, add air via automatic secondary air damper.

With reference to figure 5, in the first volatile matter sharing system 400, coke oven 105A with 105B passes through first and is connected tunnel 405A fluid connection, and coke oven 105B with 105C is connected tunnel 405B fluid by second and connects, and coke oven 105C with 105D is connected tunnel 405C fluid connection by the 3rd.As shown in the figure, 4 coke ovens 105A, B, C are all communicated with via being connected the mutual fluid in tunnel 405 with D, but during the normal operating conditions of coke oven, connect the preferred arbitrary place be connected to by coke oven fluid above coke bed upper surface, tunnel 405.Alternatively, fluid connects more or less coke oven 105.Such as, coke oven 105A, B, C can be connected in pairs with D, such that by first, coke oven 105A with 105B is connected that tunnel 405A fluid connects and coke oven 105C with 105D is connected tunnel 405C fluid connection by the 3rd, eliminate the second connection tunnel 405B.Each connection tunnel 405 is all through the share common sidewalls 175 (in order to the object described, mentioning coke oven 105B and 105C) two coke ovens 105.Connect tunnel 405B provides fluid be communicated with and provide fluid to be communicated with between two furnace chambers 185 and the sending down abnormally ascending tube passage 200 of coke oven 105C between the furnace chamber 185 and the furnace chamber 185 of coke oven 105C of coke oven 105B.

The coke oven of fluid connection is controlled (such as by the furnace pressure in biasing adjacent coke oven or furnace ventilation, coke oven 105B and 105C) between the flow of volatile matter and hot gas, make the hot gas in high pressure (low ventilation) coke oven 105B and volatile matter flow into low pressure (high ventilation) coke oven 105C by being connected tunnel 400B.Alternatively, coke oven 105C to be high pressure (low ventilation) coke oven and coke oven 105B be low pressure (high ventilate) coke oven and volatile matter is transferred to coke oven 105B from coke oven 105C.The volatile matter that will shift from high pressure (low ventilation) coke oven can from the furnace chamber 185 of high pressure (low ventilation) coke oven, sending down abnormally ascending tube passage 200 or furnace chamber 185 and sending down abnormally ascending tube passage 200.Volatile matter mainly flows in sending down abnormally ascending tube passage 200, but may in one " stock " volatile matter, intermittence flow in furnace chamber 185 in an unpredictable manner, this depends on ventilation between the furnace chamber 185 of the furnace chamber 185 of high pressure (low ventilation) coke oven 105B and low pressure (high ventilate) coke oven 105C or pressure difference.Volatile matter is transported to sending down abnormally ascending tube passage 200 and volatile matter is supplied to sole flue 205.Realize ventilating by the uptake baffle plate 230 regulated and each coke oven 105B and 105C is connected and be biased.In some embodiments, controlled to be biased with the ventilation in coke oven 105 between coke oven 105 by ventilation automatic control system 300.

In addition, connect tunnel control valve 410 can be positioned to connect in tunnel 405 to control the fluid flow rate (in order to the object described, coke oven 105C and 105D being mentioned) between two adjacent coke ovens 105 further.Control valve 410 comprises baffle plate 415, and it can be positioned fully open and fully closed being permitted and multipointly arbitraryly sentence the fluid flow rate changed by connecting tunnel 405.Control valve 410 can Non-follow control or can be automatically controlled valve.Baffle plate 415, from the instruction of controller (such as, the controller 370 of ventilation automatic control system 300) receiving position, is moved on to specific position by automatically controlled valve 410.

With reference to figure 6, in the second volatile matter sharing system 420,4 coke ovens 105E, F, G are connected by sharing tunnel 425 fluid with H.Alternatively, more or less coke oven 105 is connected by one or more shared tunnels 425 fluid.Such as, coke oven 105E, F, G can be connected in pairs with H, such that by first, coke oven 105E with F shares that tunnel fluid is connected and coke oven 105G with 105H shares tunnel fluid by second and be connected, less than connection between coke oven 105F and 105G.Centre tunnel 430 passes the top 180 of each coke oven 105E, F, G and H so that furnace chamber 185 fluid of coke oven is connected to shared tunnel 425.

Similar with the first volatile matter sharing system 400, the coke oven of fluid connection is controlled (such as by the furnace pressure in biasing adjacent coke oven or furnace ventilation, coke oven 105G and 105H) between the flow of volatile matter and hot gas, make the hot gas in high pressure (low ventilation) coke oven 105G and volatile matter flow into low pressure (high ventilate) coke oven 105H by sharing tunnel 425.The flow of volatile matter in low pressure (high ventilate) coke oven 105H can be controlled further VM is supplied to furnace chamber 185, sole flue 205 via sending down abnormally ascending tube passage 200, or furnace chamber 185 and sole flue 205.

In addition, share tunnel control valve 435 and can be positioned shared tunnel 425 to control the fluid flow rate along shared tunnel (such as, between coke oven 105F and 105G).Control valve 435 comprises baffle plate 440, and it can be positioned fully open and fully closed being permitted and multipointly arbitraryly sentence the fluid flow rate changed by shared tunnel 425.Control valve 435 can Non-follow control or can be automatically controlled valve.Baffle plate 440, from the instruction of controller (such as, the controller 370 of ventilation automatic control system 300) receiving position, is moved on to specific position by automatically controlled valve 435.In some embodiments, multiple control valve 435 is positioned in shared tunnel 425.Such as, control valve 435 can be positioned between two or more coke ovens 105 between adjacent coke oven 105 or in groups.

With reference to figure 7, the 3rd volatile matter sharing system 445 combines the first volatile matter sharing system 400 and the second volatile matter sharing system 420.As shown in the figure, four coke ovens 105H, I, J and K via be connected tunnel 405D, E with F and via shared tunnel 425 mutually fluid be connected.In other embodiments, the various combination via two or more coke ovens 105 connecting tunnel 405 and/or shared tunnel 425 connection is used.The flow of volatile matter and hot gas between the coke oven that furnace pressure between the coke oven connected by biased fluid or furnace ventilation control fluid are connected.In addition, the 3rd volatile matter sharing system 445 can comprise at least one and connect tunnel control valve 410 and/or at least one shared tunnel control valve 435 with the fluid flow rate between control linkage coke oven 105.

Volatile matter sharing system 445 provides the selection that two volatile matter share: via connect the top-sending down abnormally ascending tube passage in tunnel 405 share and top-top via shared tunnel 425 shared.Like this to the conveying of coke oven 105 receiving volatile matter, stronger control is provided to volatile matter.Such as, at sole flue 205, but volatile matter may be needed in non-furnace chamber 185, or vice versa.Independent tunnel 405 and 425 is respectively used to top-sending down abnormally ascending tube passage and top-top share, guarantees that volatile matter reliably can transfer to tram (that is, arriving furnace chamber 185 or sole flue 205 via sending down abnormally ascending tube passage 200).Ventilation if desired in biased each coke oven 105, pushing up as required-volatile matter is carried on sending down abnormally ascending tube passage and/or top-top.

For these three volatile matter sharing systems 400,420 and 445 all, during transfer volatile matter, importantly control the oxygen concn in coke oven 105.When sharing volatile matter, importantly in the region (such as, furnace chamber 185 or sole flue 205) receiving volatile matter, there is suitable oxygen concn.Oxygen will burn volatile matter more more than needs too much.Such as, if volatile matter be added to furnace chamber 185 and there is too many oxygen, then volatile matter will in furnace chamber 185 Thorough combustion, make furnace chamber temperature be increased to more than target furnace chamber temperature and cause not having the volatile matter shifted to enter sole flue 205 by furnace chamber 185, this can cause sole flue temperature lower than target sole flue temperature.For another example, when top-sending down abnormally ascending tube passage shares, importantly guarantee to exist in sole flue 205 suitable oxygen concn with the volatile matter of transfer of burning, or sole flue temperature can not realize due to the potential increase shifting volatile matter.By regulating primary air baffle plate 195, secondary air baffle plate 220 and the tertiary air baffle plate 229 separately independently or in various combination, realize the control to oxygen concn in coke oven 105.

Volatile matter sharing system 400,420 and 445 can be incorporated to newly-built coke oven 105 or can be used as remodeling and add in existing coke oven 105.Volatile matter sharing system 420 and 445 seems to be more suitable for improving existing coke oven 105.

Density can be used relatively low (such as, proportion (" sg ") is between 0.75 and 0.85) loose coking coal as coal input or use high-density (" making firm by ramming the ") coking coal of compacting and non-coking coal mixture to input as coal, operation coking equipment.Coal tamping forms the briquette of density relatively high (such as, between 0.9sg and 1.2sg or higher).Coal release for for coke making process confession fuel volatile matter discharged with different rates by loose coking coal and coal tamping.The speed ratio coal tamping of loose coking coal release volatile matter is much higher.As shown in Figure 8, the speed of coal (be shown as the loose coking coal 450 of dotted line or be shown as the coal tamping 455 of solid line) release volatile matter declines after coking cycle midway (such as, entering coking cycle about little of an and a half hours) reaches peak value.As shown in Figure 9, because the speed of volatile matter release is higher, so the speed filling the coke oven heating of loose coking coal (being shown as solid line 460) will reach higher temperature than the coke oven of dress coal tamping (being shown as dotted line 465) faster (that is, reaching target coking temperature sooner).Preferably measurement target coking temperature and be shown as broken line 470 near furnace roof.The speed of volatile matter release lowlyer causes than in the stove filling loose coking coal, and the furnace temperature on top is lower, and the time reaching coke oven target temperature is longer and coking cycle is longer.If coking cycle time lengthening is too of a specified duration, then coal tamping may coking completely, generation green coke.Compared with filling the coke oven of loose coking coal, the speed temperature that is longer and furnace roof heat-up time that is lower, that reach target temperature of tamping coke furnace volatile matter release is lower all to be impelled the coking cycle time of making stove firm by ramming longer and may produce green coke.The volatile matter sharing system 400,420 and 445 shared between the available coke oven that volatile matter is connected at fluid overcomes these shortcomings of tamping coke furnace.

During use, volatile matter sharing system 400,420 and 445 makes volatile matter and hot gas from being in coking mid-term and the different coke-oven 105 just having enclosed coal tamping transferred to by the coke oven 105 having reached target coking temperature.This contributes to the relatively cold faster heating of coke oven 105 of just dress, and can not cause disadvantageous effect to the process of coking of coking coke oven in mid-term 105.As shown in Figure 10, according to the exemplary of the method 500 of volatile matter shared between coke oven, be that the first coke oven loads coal tamping (step 505).The work (step 510) volatile matter is transferred to the first coke oven (step 515) from the second coke oven at target coking temperature or more of second coke oven.Wherein a kind of volatile matter sharing system 400,420 and 425 is used to shift volatile matter between coke oven.By the furnace ventilation of biased two coke ovens, according to the position of at least one control valve 410 and/or 435 between two coke ovens, or the combination of two kinds controls speed and the volume of volatile matter stream.Optionally, add to the first coke oven the volatile matter (step 520) that additional air shifts from second stove with Thorough combustion.Additional air can be added as required by primary air entrance, secondary air entrance or tertiary air entrance.Add the burning strengthened near furnace roof via primary air entrance and raise throat temperature.Add the burning strengthened in sole flue via secondary air entrance and raise sole flue temperature.Add furnace temperature in the first coke oven and furnace temperature rate of increase (step 525) at the volatile matter of transfer in the first coke oven combustion, thus make the first coke oven reach target coking temperature quickly and decrease the coking cycle time.Furnace temperature in second coke oven reduces, but remains on more than target coking temperature (step 530).Figure 11 describes throat temperature according to elapsed time in the coking cycle of each coke oven, to show the throat temperature graphic representation of two coke ovens sharing volatile matter according to method 500 between coke oven.First coke oven is dotted line 475 relative to the Temperature displaying of elapsed time in the first coking by coke oven cycle.Second coke oven is solid line 480 relative to the Temperature displaying of elapsed time in the second coking by coke oven cycle.The time starting volatile matter to be transferred to the stove of just having made firm by ramming is have recorded along time shaft.

Alternatively, volatile matter can be shared run overheated coke oven to cool between two coke ovens.Temperature sensor (such as, furnace temperature sensor 320, sole flue temperature sensor 325, rising airway temperature sensor 330) detect superheat state in the first coke oven (such as, close, be in or higher than the highest furnace temperature) and responsively, volatile matter is transferred to the second cold coke oven from hot coke oven.According to the cold coke oven of temperature identification that temperature sensor (such as, furnace temperature sensor 320, sole flue temperature sensor 325, rising airway temperature sensor 330) senses.Coke oven should fully lower than superheat state to adapt to raise transferring to from hot coke oven the temperature that cold coke oven causes by volatile matter.By removing volatile matter from hot coke oven, the temperature of hot coke oven drops to below superheat state.
